Hamas and Israel are at war and the land beneath their citizens' feet is crying. As it does, an incredible marvel -- while not entirely new-- is happening, and that is tweeting behind the lines. The idea that Palestinians and I, a Jewish community worker in Toronto in 2014, are bantering back and forth while bombs and missiles fall in Israel and Gaza is astounding.

As military strikes between Israel and Gaza continued with the deaths of 11 Palestinian civilians on Sunday, a complicated Internet battlefront has appeared. There is an unprecedentedly transparent wave of social media propaganda by both sides.
